无序双层阵列中的安德森局域化:常规光子晶体与超材料
Anderson Localization in Bi-layer Array with Compositional Disorder: Conventional Photonic Crystals versus Metamaterials
摘要:
已推导出的本地化长度为一维双层结构的随机扰动的折射率为每种类型的层。主要的注意力是传统的材料和那些由混合的右手和左手材料之间的比较。结果表明,这两种情况下的本地化长度描述的通用表达式。数值模拟结果证实了分析结果。
英文摘要:
The localization length has been derived for one-dimensional bi-layered structures with random perturbations in the refractive indices for each type of layers. Main attention is paid to the comparison between conventional materials and those consisting of mixed right-hand and left-hand materials. It is shown that the localization length is described by the universal expression for both cases. The analytical results are confirmed by numerical simulations.
